lowing is a specification;

This invention relates to certain new and useful improvements in rockingcleans and has part1cular reference to the provision of simple andefficient means for enabling the partly broken away,

occupant of the chair to produce, by foot operation, cooling blasts ofair in hot weather.

The invention broadly contemplates the provision of a foot actuatedbellows suitably connected with a vertically disposed perforated outletpipe which is centrally arranged between the vertical rungs of the chairback with its perforations disposed so as to allow passage of airtherefrom onto a persons back and head.

With the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists inthe novel form, combination and ar rangement of parts hereinafter morefully described in connection with the accompanying drawing. 1

In the drawing wherein like reference characters indicate correspondingparts throughout the several views.

Figure 1 is a side elevational view of a rocking chair constructed inaccordance with the present invention, partly broken away.

Fig. 2 is a front elevational view thereof,

Fig. 3 is a transverse sectional view taken substantially upon lineIII-J11 of Fig. 1,

Fig. i is a vertical sectional view taken substantially upon line IV-IVof Fig. 2,

and

Fig. 5 is an enlarged sectional view taken substantially upon line V-Vof Fig. 2.

Referring more in detail to the several views, the present inventioncomprises a rocking chair having the ordinary bottom or seat 5 rigidlysecured to the four supporting legs 6 which have the arm rests 7 securedupon the upper ends thereof and which are braced by suitable rungs 8.The lower ends of the legs 6 are fastened to suitable rockers which areof laminated form comprising an.

upper wood layer 9, two rubber layers 10 therebeneath, and a metalliclayer 11 between the rubber layers, secured together by any suitablefasteners such as indicated at 12. Thls form of rocker will besubstantlally noiseless and provide a cushion effect -during therockingoperation.

The upper member 13 of. a bellows is rlgldly fastened beneath the chairseat 5 and 1ts lower member let is hinged as at 15 for movementtowardand away from the member 13 thereof in the usual manner. The lowermember 14 of the bellows is provided with the usual inlet flap valves16, and'the bellows is open at its rear edge in communication with amanifold 17 formed bya transverse tubular rung positioned attlie rearedge of the seat 5. The manifold 17. is connected at its ends to anothertubular horizontal manifold 18 positioned above thesame by providingpassages in the adjacent portions ofthe side rails 19 of the chair backas indicatedat 20 in Fig.2, and the manifold 18 constitutes the lowerrail of the chair back and is connected to the top rail 21 thereof bythe usual slats or bars 22.

An outlet pipe 23 communicates with the central portion of the uppermanifold 18 and extends upwardly from the latter. The outlet pipe 23 isprovided with a cross head 24 at its upper end and this head is seatedin a groove provided in the front face of the upper rail 21 of thechair-back as shown in Fig. 5 The outlet pipe 23 and its head 24 isprovided'with a number of perforations 25 so as to permit the passage ofair there through onto the persons back and head occupying the chair andmanipulating the bellows as will presently be described.

The rockers of the chair are connected by a horizontally disposed rod 26extending transversely therebetween, and afoot lever having end hubs 27journaled upon the rod 26 is provided with rearwardly extending arms 28which are slidably and pivotally connected to the lower hinged member 14of the bellows by pin and slot connections 29. This foot lever includesa treadle or pedal 30 which extends forwardly from the hubs 27, inconvenient position for receiving the feet of the occupant of the chairwhereby. the foot lever may be rocked for actuating the bellows as willbe apparent.

It will be seen that when the pedal 30 is. moved downwardly the arms 28will be swung upwardly for moving the lower bellows members 14 towardthestationary member 13 thereof, thereby forcing air into the manifolds17 and 18 to the outlet pipe 23 and through the perforations 25 thereof.

This will effectively serve to cool the occupant of the chair in warmweather without rockers, a back for said chair comprising vertical slatsand horizontal upper and lower rails connected thereby, said upper railbe ing centrally recessed, the lower rail consisting ofa tubularmanifold, a bellows beneath the seat member and interiorly connectedwith the interior of said lower rail,

; an outlet pipe for air from the bellows connected with the interior ofsaid lower rail at the center of the latter and extendingup. wardlytherefrom, said outlet pipe having perforatlons therethrough, means foractuating said bellows, and a cross head upon the upper end of saidoutlet pipe seated in forations therethrough.

including foot rest said recess of the top rail and having per- 2. Arocking chair including a seat mem her having supporting legsprovidedwith rockers, a back for said chair comprising vertical slatsand horizontal upper and lower rails connected thereby, said upper railbe- 'ing centrally recessed, the lower rail consisting of a tubularmanifold, bellows be neath the seat member and interiorly connected withthe interior of said lower rail,-an outlet pipe for air from the bellowsconnected. with the interior of said lower rail at the center of thelatter and extending upwardly therefrom, said outlet pipe havingperforations th t rough, means for actuating said bellows, across headupon'the upper end of said outlet pipe seated in said cess the top railand having perforations therethrough,said hell. we actuating means:

pivoted to the rockers, said bellows including a vertically swingablelower member, and a pair rearwardly errtending arms rigid with the footrest and slidably and pivotally connected to said swingahle bellowsmember. 7 a
